Gluteal Region Flashcards
Sacrotuberous and Sacrospinous ligaments
What are the parts of the femur?

What are the branches of the Internal Iliac artery (comes from common iliac)?
This breaks into an anterior and posterior division. The anterior division will branch into the inferior gluteal and internal pudendal. The posterior will branch into the the superior gluteal.
What are the branches of the external illiac artery (comes from common iliac)?
The external branches into the deep and femoral artery. The femoral goes off to become popiteal after passing through hiatus, and the deep artery of the thigh branches into medial circumflex which wraps around neck of humerus and lateral circumflex taht wraps between lesser and greater troch.
What are some vascular supplies to femoral head?
acetabular , obturator, retinacular arteries, and the two circumflexes
What are the 5 branches of the popiteal artery?
superior lateral genicular, inferior lateral genicular, inferior medial genicular, and superior medial genicular
Where does femoral and obturator nerve come from?
femoral comes from L2-L4 dorsal division
obturator comes from L2-L4 ventral division
What are the branches of common fibular and tibial nerve (come from sciatic nerve)?
tibial branches to hamstrings and adductor magnus and common fibular branches into short head of biceps femoris
Which nerves encompass nerve to quadratus femoris and inferior gemellus?
anterior L4-S3
Which nerves encompass nerve to obturator internus and superior gemellus?
anterior L5-S3
Which nerves encompass tibial nerve?
anterior L4-S3
Which nerves encompass common fibular nerve?
posterior L4-S2
Which nerves encompass superior gluteal nerve?
L4-S1
Which nerves encompass inferior gluteal nerve?
L5-S2
Which nerves encompass branch to piriformis?
S1-S2
What are attachments and nerves of gluteus maximus?
attaches to illium and gluteal tuberosity. Innervated by inferior gluteal nerve
What are attachmetns and innervations of gluteus medius?
illium and greater troch, innervated by superior gluteal nerve
What are attachments and innervation of gluteus minimus?
illium and greater troch, innervated by superior gluteal nerve
What is attachments and innervation of tensor fascia lata?
ASIS and IT band, innervated by superior gluteal nerve
What is attachments and innervation of piriformis?
sacrum and sacrotuberous ligament, greater troch, and innervated by anterior rami
What are the quadratus femoris attachments and innervation?
ischial tuberosity and intertrochanteric line, innervated by nerve to quadratus
What are superior gemellus attachments and innervation?
ischial spine and greater troch, and innervated by obturator internus
What is inferior gemellis attachments and innervation?
ischial tuberosity and greater trochanter, innervated by nerve to quadratus femoris
What makes up triceps coxae?
superior gemellus, inferior gemellus, and obturator internus
What makes up triceps coxae?
superior gemellus, inferior gemellus, and obturator internus
Which muscles do medial and lateral rotation?
Medial: is tensor fascia lata, gluteus minimus and medius
Lateral is quadratus femoris, glute max, piriformis, triceps coxae, and obturator externus
What is function of iliotibial tract?
stabilizes the pelvis in frontal plane during heel strike and mid swing so you don’t fall over
What protects femoral neck?
fibrous capsule, acetabular labrum, orbicular zone, and retinacula
What are attachments of semitendinous and innervation?
ischial tuberosity and medial tibia, innervated by tibial sciatic nerve
What are attachments of semimembranosus and innervation?
attaches to ischial tuberosity and tibial condyle, innervated by tibial sciatic nerve
What are attachments and innervation of biceps femoris?
Long head attaches to ischial tuberosity and lateral head of fibula, innervated by tibial sciatic nerve. Short head attaches to linea aspera and lateral head of fibula, innervated by fibular sciatic nerve
What is the function of the hamstrings?
they flex the leg which involves extending the hip and flexing the knee
